The Roman Army A to Z: probatio

probatio (f. pl. probationes Mod.)

The examination of a new recruit, whereby his legal status and eligibility were verified and a physical examination carried out. If successful, a certificate was then issued by the office of the provincial governor concerned and the recruit given a viaticum and despatched to a unit. Potential cavalry horses evidently underwent a similar process. The term is inferred from the use of the phrase probatum/os a me by the certifying officer. RMR 83; 87; 99; 100. [Goldsworthy 2003]
